Agastache plant named ‘AGA 104’

ABSTRACT

A new and distinct cultivar of  Agastache  plant named ‘AGA 104’, characterized by its compact, upright and open plant habit; freely branching habit; vigorous growth habit; long inflorescences with pale orange-colored flowers; freely and continuous flowering habit; and good garden performance.

Botanical designation: Agastache mexicana.

Cultivar denomination: ‘AGA 104’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Agastache, botanically known as Agastache mexicana and hereinafter referred to by the name ‘AGA 104’.

The new Agastache is a product of a planned breeding program conducted by the Inventor in Hann. Münden, Germany. The objective of the breeding program was to create new Agastache cultivars with large and dense inflorescences and attractive flower coloration.

The new Agastache originated from an open-pollination during the summer of 2003 in Hann. Münden, Germany, of an unnamed selection of Agastache mexicana, not patented, as the female, or seed, parent with an unknown selection of Agastache mexicana as the male, or pollen, parent. The new Agastache was discovered and selected by the Inventor as a single flowering plant within the progeny of the stated open-pollination in a controlled environment in Hann. Münden, Germany during the summer of 2004.

Asexual reproduction of the new Agastache by vegetative cuttings in a controlled environment in Hann. Münden, Germany during the winter of 2004, has shown that the unique features of this new Agastache are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

The cultivar AGA 104 has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment and cultural practices such as temperature and light intensity without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘AGA 104’. These characteristics in combination distinguish ‘AGA 104’ as a new and distinct cultivar of Agastache:

-   -   1. Compact, upright and open plant habit.     -   2. Freely branching habit.     -   3. Vigorous growth habit.     -   4. Long inflorescences with pale orange-colored flowers.     -   5. Freely and continuous flowering habit.     -   6. Good garden performance.

Compared to plants of the female parent selection, plants of the new Agastache are more compact and differ in flower coloration.

Plants of the new Agastache can also be compared to plants of the cultivar Apricot Sprite, not patented. In side-by-side comparisons conducted in Hann. Münden, Germany, plants of the new Agastache and the cultivar Apricot Sprite differed in the following characteristics:

-   -   1. Plants of the new Agastache were larger than plants of the         cultivar Apricot Sprite.     -   2. Plants of the new Agastache had longer inflorescences than         plants of the cultivar Apricot Sprite.     -   3. Plants of the new Agastache had larger and lighter         orange-colored flowers than plants of the cultivar Apricot         Sprite.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying colored photographs illustrate the overall appearance of the new Agastache, showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Colors in the photographs may differ slightly from the color values cited in the detailed botanical description which accurately describe the colors of the new Agastache.

The photograph at the bottom of the sheet comprises a side perspective view of a typical flowering plant of ‘AGA 104’ grown in a container.

The photograph at the top of the sheet is a close-up view of a typical inflorescence of ‘AGA 104’.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photographs and following observations, measurements and values describe plants grown in Litchfield, Mich. during the late spring and summer and under commercial practice in a polyethylene-covered greenhouse. During the production of the plants, day temperatures ranged from 20° C. to 24° C. and night temperatures ranged from 16° C. to 18° C. After planting, plants were pinched one time. Plants had been growing for about six months when the photographs and description were taken. In the following description, color references are made to The Royal Horticultural Society Colour Chart, 1995 Edition, except where general terms of ordinary dictionary significance are used.
